A case study focuses on a single individual, a small group of people, or occasionally a single event. You'll be conducting qualitative research to find specific details and descriptions of how your subject is affected. 1  For example, a medical case study might study how a single patient is affected by an injury.ou may be asked to prove that the case study does no harm to its participants. 1  Follow this step even if you are conducting a retrospective case study. 2  In some cases, publishing a new interpretation can cause harm to the participants in the original study.
Formula or Equation Note. The incremental capital output ratio (ICOR) is defined as the ratio between investment in some previous period(s) and the growth in output in the subsequent period.Needless to say, ICOR calculation is based on constant price data.ormula or Equation Note.

It can be expressed as the ratio of output to inputs used in the production process, i.e. output per unit of input. When all outputs and inputs are included in the productivity measure it is called total productivity. Outputs and inputs are defined in the total productivity measure as their economic values.he production performance can be measured as an average or an absolute income. Expressing performance both in average (avg.) and absolute (abs.) quantities is helpful for understanding the welfare effects of production. For measurement of the average production performance, we use the known productivity ratio.
